Install Ruby, Sass and Compass

Sass is a CSS preprocessor which adds nested rules, mixins, variables, selectors and more. Sass generates well formatted CSS and makes your stylesheets easier to organize and maintain. Compass is a framework build on the top of the Sass and it makes working with Sass even easier. Both Compass and Sass are Ruby gems so you’ll need to have Ruby on your linux vps

.

RVM (Ruby Version Manager) can handle the installation and management of multiple Ruby environments.
